Collagenous fibroma (desmoplastic fibroblastoma) is a recently described rare benign tumor affecting mainly males in the fifth through seventh decades. This tumor occurs predominantly in the peripheral sites, with predilection for upper and lower extremities. The patients present with a painless mass of involving subcutis, with one quarter of all cases involving skeletal muscle. Both radiograph...

INTRODUCTION To present a case of a child with a desmoplastic fibroma of the vidian canal, compressing the vidian nerve. CASE REPORT A 12-year-old girl with several years' history of right-sided facial pain was referred to our institution. Magnetic resonance imaging and computed tomography scans showed an expansile mass involving the right vidian canal. The patient underwent a complete endosc...

The desmoplastic variant of ameloblastoma is a rare form of ameloblastoma characterized by unique radiographic and histologic features. A 46-year-old female was referred to our hospital, complaining of swelling in the left upper lip area. Radiographic findings revealed an ill-defined multilocular lesion with a large cystic lesion and thick sclerotic trabeculae on the left anterior maxilla. Afte...

fibrous, soft-tissue tumor first described by Evans (1) in 1995. This tumor is clinically and morphologically distinct and was deemed completely benign in a few reported series (1-3). There have also been published case reports on the MR features of desmoplastic fibroblastoma (4-8). We herein present a case of desmoplastic fibroblastoma with special focus on the MR findings, because they are di...

Ameloblastoma is usually considered a homogenous neoplasm and is thought of as the most primitive of all odontogenic neoplasms. However, detailed investigations have proven clinicopathological diversity in a significant number of cases, thus mounting the evidence in favor of considering ameloblastoma as a mysterious lesion. The purpose of this article is to report a unique case of desmoplastic ...

Desmoplastic fibromas are rare, benign bone tumours, which often behave in a locally aggressive manner. In the head and neck region they are most commonly seen in the mandible and have been treated in various ways. We present an unusual presentation of the lesion, which was subsequently treated by the less commonly used technique of enucleation, with good results.
